CAN-LABELING MACHINE.

Application filed November 5, 1917.

To all whom it may concern:

Be it known that Anvil) P. EKVALL and HERMAN STAKE, both citizens of the United States, residing at WVorcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Can-Labeling Machines, of which the following is a specification.

Our present invention relates'to a novel construction and organization of mechanism for gumming or applying adhesive substance to the end portion of the labels, the same being adapted for use on that class of can-labeling machines wherein the labels are aflixed by rolling the cans over the pack of labels on a label-supply holder.

The prime object of our invention is to provide an eflicient, convenient and desirable gum-applying means that can be operated at a high rate of speed. Also, to afford a can-controlled mechanism of the character specified, having means for interrupting the gumming action whenever a can is absent from the regular order of serial advancement.

These objects we attain by mechanism the nature, organization and mode of operation of which is more fully set forth in the following detailed description, with reference to the accompanying drawings, (three sheet-s) wherein Figure 1 represents a front side elevation. Fig. 2 is a rear elevation; Fig. 3 a vertical transverse section through the oscillating shaft and label box, at line- X X on Fig. 1. Fig. 4 is a detail view of the cam which actuates the applier-supporting lever. Fig. 5 is a detail view of the cam and connections for tilting the gumapplier. Fig. 6 represents a top plan view of the mechanism with the gum-applier at position as when in contact with the label.

Fig. 7 is a horizontal sectional plan view of the shafts, cams and levers below the gum reservoir, with dot-and-dash lines indicating the position of the label-box and the relative location of the gum-applier when retracted. Fig. 8 is an outline diagram indicating the arrangement of the drive-gear- Specification of Letters Patent.

ing; and Fig. 9 is a diagrammatic View illustrating the action of the gum-applier.

As illustrated this mechanism is more especially adapted to a can-labeling ma chine of the general character set forth in Letters Patent No. 1,238,? 10, granted us August 28, 1917 but may be employed upon other labeling machines in similar manner.

In-referring to the drawings, numeral 20 denotes the supporting bed or frame, which may be of any suitable construction; B the over head propelling belts, which may be mounted on pulleys B and operated as heretofore employed; and R indicates the runway along which the cans C roll while being labeled.

Numeral 10 indicates the label-box for containing the supply of labels L, which are supported therein, backs upward, upon a vertically movable plate 11, having an elevating standard 12 with which any well known or suitable elevator mechanism may be combined for keeping the top of the label pack at approximately uniform level with the runway, as labels are taken therefrom.

Any well known or suitable means can be employed for touching the top surface of the pack and for controlling the action of the elevator mechanism, but said elevating and elevator-controlling devices, not being claimed as of our present invention, are not herein shown.

The front side 1O of the label-box is removable to facilitate charging the labels into said box, and can be retained in posi tion by one Or more thumb screws I or other equivalent fasteners.

Numeral 13 (Fig. 6) indicates the primary gunrapplying roll or device for imprinting adhesive substance upon the surface of the can,'as heretofore practised; it being located in such relation that the rotation of the can brings the gummed area down upon the first end of the uppermost label in the labelbox, causing said end to adhere to, and be picked up by the rolling can, as will be fully understood.

The term gum or gumming, as employed in this specification, is intended to include as an equivalent, the use of paste, glue, mucilage or any other suitable adhesive substances such as may be employed for sticking labels upon the articles to which they are affixed.

Numeral; 15 indicates the tracks along the sidesof the label-box, upon which. the rims of the cams roll; and 16 indicates parallel side guards or rails defining the runway, and for embracing the ends of the cans to keep them in proper alinement with the labels.

The tracks upon whichthe. cans roll are.

preferably formed with a depression 14 at thefront endgof the label-box coincident to the pick-u position, to allow the gummed spotsupon the can topress more.firml-y upon the label.

over the. gum-applier ydevices.

Numeral l7 indicates the gum reservoirsupportednpon and closely adjacent thetend of; the, label-box, the base. of::w\hich. is ex;

of; the pack. oflabels whether the labelbox is adjusted for longer or shorterlabels, as required for varlous sizes of cans. In the.

present instance the reservoiris removably retained in positionby engaging lugs. a, av notched step; e .and a spring pressedlatch indicates-a transfer-roll arranged parallel: with the delivery roll 2 to takeygumth ere from; and. issupported to turn in-bearmgs preferably-attached to thefront part of the reservoir. This transfer-roll is located outside-the end wall of the label-box, adjacentthe top corner thereof, and. slightly below.

the; top-plane oftheppackbfi "labels; said parts being respectively positioned substantially as illustrated. The top of the end. wall of the labelbox is best made vslightly lower than; the top plane. of the packi'ofalabels. (See- Figs. 1 and 9.-),

Supported in suitableibearings or brackets 21, attached to the extended 'baselO of the label-box 10; :we arrangea rotatable-shaft 23, and an oscillative shaft 24; the formeribee The tracks are also preferably slightly arched at 18, where the can passes.

ing operated by a sprocket and chain 26, or other suitable means, from the main drive 28, or other moving part of the can-labeling machine. The shaft 2th is provided with an arm 25 having a stud-roller 25 thereon that engages with a cam 30 fixed on the shaft 23, whereby oscillative or rocking action is imparted to the shaft 2.4: and parts connected therewith, synchronally. A. spring. 27. is provided for-keeping the roller25 against the face of the cam 30 and for moving the arm-and-connected parts in one direction, while the cam controls their movement and actuates them in the other direction.

Fixed upon theshaft 24' and extending upward past the ends of the gum-reservoir,

are two carrier-arms or'supporters31 and 31 having between their upperends a transversely disposed gum-applying element, the

bar or;p1ate 32,0f which is ivoted-or;l1ingedl-y supportedat its ends 3 with the carrierlmeans.

Fig, 5, soas to clearthe-roll-driving gears. Upon the bar 32 {there isa forwardly projecting. open plateor gumrapplier member 5, having a fiat under surface corresponding in form and sizeto. the area. of thatportion of the label which is tobev coated with; gum or adhesive substance; this being preferably a rectangular strip across. the rear end of the label, about 1 one-half inch,more1 or less, in. width. The gum-applier plate 5 and bar 32.

maybe integral {and-solid; but preferably the plate is provided :with a back member 6- that is firmly attached to. the bar 32 by screws. 00, or other approved fasteners the.

gum-applier-plate and back member being for lightness of structure formed open at The bar 32 is provided with a. rigid or integrall-yattached b'ackwardly prothe center and integrally: united .byslightl'y arched arms :7. The gum-applier 1 projects for some distance. forward from thebar .sufiL.

cientlyto reach. over .thegum rollers,-,as illustrated, forprinting gum upon thelabels.

Numeral 35 indicates a cam fixed upon. therotating shaft 1 23; and 36 is an-upwardly and downwardly acting lever or arm, having a stud. roller 36 that engages said cam. A

suitable spring 37 is-provided for effecting.

movement in opposition to the cam action.

The fulcrum hub of said armispreferably mounted to turn looseupon the oscillating shaft 24t Pivotallyattached to the arm 36' there is a connector-or link element 39, theupper end of which is pivotallyvattached to the arm 34 of the bar 32 for tilting or -rock-. ing'the gumrapplier onits carrier by actuationof-thearm 36-by the cam 35. The connector isprovided with an intermediate hinging joint 40 adaptechto permit back--v ward knuckle-joint zfiexure, but .to resist forr ward flexure beyond its straight alinernent, it having contact lugs or stop surfaces 41 therefor. A suitably arranged spring 42 is combined therewith for reestablishing its straight alinement when the flexing force is relieved. A laterally projecting pin or lug 45 is arranged in or upon the connector bar 39 belowthe hinging joint.

At the back of the label-box 10, and projecting up through the track 15 upon which the cam C rolls, there is arranged a movable detent or depressible can-actuated member 46 which is connected with one arm of a lever 47, fulcrumed on a stud 48, and having a rearward arm extending to and terminating adjacently in front of the pin 45 fixed on the connector bar. The detent 46, when free, is normally held at elevated position by a suitably arranged spring 49.

The gum-roll 2 and transfer roll 3 are given rotative movement from the shaft 23 by a train of gearing preferably arranged as indicated by the diagram Fig. 8; and comprising a sprocket 51 fixed on shaft 23, a chain 52 connecting therefrom to a sprocket 53 and spur gear 54 mounted on a stud fixed on the frame; an intermediate stud-supported gear 55 meshing with said spur gear; a gear 56 fixed on the axle of the gum-roll 2 and engaging with said intermediate gear; and a gear 57 upon the axle of the transferroll 3, meshing with the gear on the gumroll axle, the movement of the several gears being in the direction severally indicated by the arrows.

The cans are fed into the runway R and rolled forward by the belts so that in normal action they follow each other at regular spaced intervals; the rate of their approach being timed to correspond with the cycle of action of the described gumming apparatus. The spacing may be accomplished by suitable feed-spacing mechanism; which being a separate invention is not herein described. It frequently occurs, however, that for one reason or another oneor more cans may be omitted from the regular spaced serial order while the machine is running. Such condition is provided for in the action of our improved mechanism as explained.

The operation is as follows: Assuming that the machine is running and that the parts are at the positions indicated in Fig. 1, and by full lines in Fig. 9; the can C having been primarily gummed and having picked up the first end of the label, as the can C approaches the rear end of the label-box the cam 30 upon the rotating shaft 23 actuates the lever arm 25, oscillating the shaft 24 and causing the arms 31 and 31 to swing forward, carrying the bar 32 and gum-applier 5, the face of which has been previously charged with gum or adhesive, toward the end of the pack of labels L, to

the position shown in Fig. 6. At about the same time the cam 35 actuating the lifter arm 36, raises the connector 39, which is pivoted to the backwardly projecting arm 34 of the rocking-bar 32 upon which the gum-applier 5 is mounted; thus moving or tilting the gummer face toward the label. This movement is effected approximately at the same time or just subsequent to the can C having rolled onto and depressed the detent 46 and thereby lifting the lever arm 47 thus permitting the pin or lug 45 to pass under said lever, as indicated at 45", Fig. 9, so that the connector 39 remains straight and elevates the rear end of the arm 34 to the level position, or tilting the gum-applier to bring its gum-charged face down upon the label-pack (see position 5 Fig. 9) imprinting a film of gum across the lap-end of the topmost label, just before the can 0 rolls over the same, and pulls the label from the retreating gum-applier. Further rotation of the shaft and controlling cam permits the spring 37 to return the parts to their former positions.

As the gum-applier moves rearward its face is drawn in contact with the transfer roll 3 which puts a new charge of gum upon said gum-applier ready for the succeeding action.

If, in the running of the machine, a can is omitted from the regular serial order, then the detent 46 and lever 47 will of course not be actuated. In that event, when the carrier arms and gum-applier move forward, the pin or lug 45 on the jointed connector 39 engages the end of the lever 47 and carries it upward to the position 45, Fig. 9. This causes the knuckle-joint 40 to be forced backward, (see dot-and-dash lines, Fig. 9) thereby diverting or shortening the effective length of the connection between the arm 34 and lever 36, so that the gum-applier 5 when moved forward over the end of the label-box will be tilted up to a position (5 Fig. 9) where its face cannot come in contact with the label; thus avoiding the spreading of gum upon a label when it cannot be immediately picked up by an advancing can. As the gum-applier is retracted and the parts swing backward the knuckle-joint 40 is straightened by the force of the spring 42 and the parts all return to their normal relation preparatory to the succeeding operation.

When adjusting this mechanism to accommodate different sizes of cans the only change required in the gumming means is to remove the screws m and replace the applier plate 5-6 by a corresponding plate of the desired width; a comparatively simple and inexpensive matter; the bar portion 32 of the applier, which forms its pivotal fulcrum upon the reciprocating moving carrier -members :the\ gum supply; devices-and desire to secure by Letters Patent, .is
